Prevalence and Severity Distribution of Type 2 Inflammation-Related Comorbidities Among Patients with Asthma, Chronic Rhinosinusitis with Nasal Polyps, and Atopic Dermatitis

This observational study assessed the prevalence of co-existing type 2 inflammatory conditions [T2Cs; asthma, atopic dermatitis (AD), allergic rhinitis, and chronic rhinosinusitis with nasal polyps (CRSwNP)] in patients with moderate-to-severe (M/S) type 2 asthma, M/S CRSwNP, or M/S AD, in the real-world setting. Data from 761 physicians in the US and EUR5 were sourced from Adelphi Disease-Specific Programmes covering patients with M/S asthma (n = 899), M/S CRSwNP (n = 683), and M/S AD (n = 1497). At least one T2C was identified in 66%, 69%, and 46% of M/S asthma, M/S CRSwNP, and M/S AD cohorts, respectively, and 24%, 36% and 16% had at least two T2Cs; trends were similar in the US and EUR5. In patients with M/S asthma or M/S CRSwNP, T2Cs commonly presented as mild or moderate. The comorbidity burden suggests that an integrated treatment approach is warranted to address underlying type 2 inflammation in patients with M/S type 2 diseases.
